3 Claims. (Cl. 241-1005.)

This invention relates to waste disposal apparatus of the type having mechanism for grinding and discharging waste maten'al into a plumbing system and adapted .to be mounted below a sink drain opening, and has as its principal object the provision of an improved mounting arrangement for securing such apparatus to the sink.

Further objects and advantages of the invention will become apparent as the vfollowing description proceeds, and the features of novelty which characterize the invention will be pointed out with particularity in the claims annexed to and forminga part of this specification.

Briefly stated, in accordance with one aspect of this invention there is provided mounting structure for initially securing a support ring to the drain opening sleeve of a sink including vertical studs with nuts on their lower ends, and a mounting ring on the disposer housing provided with openings having one portion for receiving the nuts and another smaller portion for receiving only the studs when the housing is partially rotated.

For a better understanding of the invention, reference may be made to the following description and the accompanying drawing in which:

Fig. l is a fragmentary elevation view, partly in section illustrating waste disposal apparatus incorporating this invention; and

Fig. 2 is a sectional view taken along the line 2-2 of Fig. 1.

Referring to the drawing, the numeral 1 designates the bottom wall of a kitchen sink having a drain opening below which waste disposer 2 may be supported. Waste disposer 2 includes a housing 3 enclosing a comminuting chamber having an inlet opening for Water and Waste material at the upper end thereof, and a tubular sleeve 4 disposed in the sink drain opening so as to support housing 3 and provide a passage between the sink and the comminuting chamber enclosed by housing 3. Waste disposer 2 is provided with suitable comminuting or grinding means at the bottom of the comminuting chamber, but inasmuch as the details of the grinding mechanism do not form a part of the present invention, they are not described herein. The inlet opening defined by sleeve 4 may be closed by any suitable drain stopper, such as stopper 5 which is adapted to rest on the circumferential seat element 6 within sleeve 4.

it will be observed that housing 3 has a circular top inlet opening aligned with the sink drain opening and that sleeve 4- not only provides a passageway from the sink to the interior of the housing but also supports the housing, being provided with a flange 7 on the upper end thereof adapted to overlie the marginal edge of the drain opening. Sleeve 4 also includes a flange or beaded portion 8 on its lower end which cooperates with the overlying flange 9 of support ring 10 in securing sleeve 4 to sink wall 1. Support ring 10 is formed from two semi-circular segments 11 and 12 which may be secured together after they are assembled on sleeve 4 by suitable fastening means such. as screws 13 threaded in radially nited States atent O i flange 17.

ISupport ring ing ring 15 so asrto compress'gasket 16 and draw flange 7 of sleeve 4 :tightly against bottom wall 1 of the sink. Thus a unitary structure is formed after segments 11 and 12 of support ring \10 have been fastened together so as to encirclersleeve t, andstuds 14 have been tightened so 'as to bear against clamping ring 15.

Formed onahe .upperlend of housing 3 is an outwardly projecting flange :17 whichcooperates with a mounting ring 18 encircling :the housing immediately below the An elongated aperture 19 is provided in mounting ring 18 .for each stud .14, each aperture including an enlarged portion 20 sutficiently large to receive aclamping nut ZIrthreaded on the end of stud 14, and also a circumferentially extending slotted portion 22 adapted to receive only stud 14. Mounting ring 13 is split with :the :abutting ends 23 and 24 slightly separated, and also the diametrically opposite portion of the ring is reduced in cross section, by means of a U-shaped slot 25 radially extending across :a portion of the ring, so that the :mounting .ring :14 may be twisted sufficiently to fit over flange I7 and frictionally engage housing 3. The opposingsurfaces of mounting ring 18 and flange 17, and also the opposing surfaces ofhousing 3 and flange 8 on sleeve 4imay be sealed :by amultiple surface circumferential gasket 26.

In assembling the structure'described above, sleeve 4 is first positioned 'in the sink drain opening with gasket 16 and clamping ring 15 placed in position as shown in Fig. 1 andcthen the two semi-circular segments of supporting ring :10 are positioned in engagement with the beaded ridge orflange .8 on sleeve 4. The support ring screws 13 are then tightened so as 'to clamp the support ring on sleeve 4, and thereafter studs 14 carried by support ring 10 are tightened so as to bear against clamping ring 15 and secure sleeve 4 against the bottom wall 1 of the sink.

Nuts 21 are then threaded on the lower ends of studs 14, and the waste disposer 2, is raised into position so that nuts 21 pass through the large openings 20 of aperture 19 in the mounting ring 18. The waste disposer 2 and mounting ring 18 are then rotated to the position shown in Fig. 2 in which studs 14 pass into the slotted portion 22 of apertures 19 and the mounting ring is supported on the nuts 21. Thus the waste disposer 2 is hung in position and the nuts 21 may then. be tightened against support ring 10 to complete the assembly.

While in the illustrated embodiment of this invention mounting ring 18 and flange 17 are separate members, these parts may be formed as a single integral member if desired. Other modifications within the true spirit and scope of this invention may occur to those skilled in the art, and I intend by the appended claims to cover all such modifications.
